Answer:
Gravity is the only force acting on a falling ball because of free fall. Since gravity is unbalanced it accelerates an object and the velocity increases as an object falls due to gravity pushing it. The acceleration due to gravity is 9.8 m/s^2.
Answer:
(a). The average current flows through the dryer is 12.5 A
(b). The resistance of the dryer is 9.6 Ω
Explanation:
Given that,
Voltage = 120 V
Power = 1500 W
(a). We need to calculate the average current flows through the dryer
Using formula of current
Where, P = power
V = voltage
Put the value into the formula
(b). We need to calculate the resistance of the dryer
Using Ohm's law
Where, I = current
Put the value into the formula
Hence, (a). The average current flows through the dryer is 12.5 A
(b). The resistance of the dryer is 9.6 Ω
Answer:
Explanation:
The time period of a simple pendulum is given by :
L is length of the pendulum and g is acceleration due to gravity
At the bottom of Death valley, g = 9.8 m/s²
We need to find the value of g if the period of the pendulum is decreased by 5.00%.
T'=(T-0.05T)= 0.95 T
So, the new value of acceleration due to gravity is .
